UNIX doesn't have "shortcuts" as you know them. And symbolic links, which some people consider similar, don't ever contain commandline parameters. You might be thinking of a shell script?

It's better to use an alias for private, simple commands like that, though. Much simpler, less mess, needs no special permissions, and has no need to create any files in sensitive or protected places. Try typing

Code:

$ alias "l=ls -lah"
$ l
...
drwxr-xr-x  3 root root 4.0K Aug 29 23:35 sound
drwxr-xr-x  2 root root 4.0K Nov 19 20:00 ssh
drwxr-xr-x  5 root root 4.0K Aug 19 06:16 ssl
drwxr-xr-x  2 root root 4.0K Aug 29 19:21 ssmtp
-r--r-----  1 root root  750 Dec 19 09:42 sudoers
-rw-------  1 root root  750 Dec 19 09:43 sudoers.tmp
-rw-r-----  1 root root 1.5K Nov 19 20:00 sysctl.conf
...
$

If that works like it does for me, you can add it to your .bash_profile:

Code:

$ echo 'alias "l=ls -lah"' >> ~/.bash_profile

...which will make it run that line automatically on login.

rpm2cpio

rpm2cpio(1)							   User Commands						       rpm2cpio(1)

NAME

       rpm2cpio - convert Red Hat Package (RPM) to cpio archive

SYNOPSIS

       rpm2cpio [file.rpm]

DESCRIPTION

       The  rpm2cpio  utility converts the .rpm file specified as its sole argument to a cpio archive on standard output. (See NOTES.) If no argu-
       ment is given, an rpm stream is read from standard input. In both cases, rpm2cpio will fail and print a usage message if the standard  out-
       put is a terminal. Therefore, the output is usually redirected to a file or piped through the cpio(1) utility.

EXAMPLES

       Example 1: Converting an rpm file

       example% rpm2cpio Device3Dfx-1.1-2.src.rpm | cpio -itv
       CPIO archive found!
       -rw-r--r--   1 root  root    2635 Sep 13 16:39 1998, 3dfx.gif
       -rw-r--r--   1 root  root   11339 Sep 27 16:03 1998, Dev3Dfx.tar.gz
       -rw-r--r--   1 root  root    1387 Sep 27 16:04 1998, Device3Dfx-1.1-2.spec
       31 blocks

       Example 2: Converting from standard input

       example% rpm2cpio < Device3Dfx-1.1-2.src.rpm | cpio -itv
       CPIO archive found!
       -rw-r--r--   1 root  root    2635 Sep 13 16:39 1998, 3dfx.gif
